1. Field of Invention
The invention relates to accessories for smoking tobacco and more particularly to a spring based pivot mechanism for ejecting a cigarette contained in a cigarette case.
2. Description of Related Art
Cigarette cases are well known devices. Typically, cigarettes are parallel arranged as one row or two vertical rows. It is often that the fingers taking out a cigarette may contact adjacent cigarettes (e.g., filter ends) unintentionally. This, however, may leave germs on the filter end and further spread germs on the filter end into the mouth while smoking. Hence, it is unsanitary.
There have been numerous suggestions in prior patents for cigarette cases having an automatic cigarette dispensing mechanism. For example, U.S. Pat. No. 5,265,717 discloses a cigarette case for automatically lighting and ejecting a cigarette contained therein. However, its mechanism incorporates many components including pivots, gears, carousel, springs, and electrical devices. Hence, it is relatively complex in constructions, costly to manufacture, trouble-prone, and unreliable in use.
Thus, it is desirable to provide a cigarette case having a simple mechanism for dispensing a cigarette contained therein in order to overcome the inadequacies of the prior art.
It is therefore one object of the invention to provide a spring based mechanism for ejecting a cigarette contained in a cigarette case by simply pivoting a trigger on a cover of the case.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
The cover 2 comprises an outer covering plate 22 and an inner separation plate 21 including a narrow first channel 211 in proximity to the front end, and a narrow second channel 212 in proximity to one corner just above the outlet 11 when the case is closed.
The cigarette ejecting mechanism is mainly provided in a space defined by the covering plate 22 and the separation plate 21. The mechanism comprises an L-shaped ejector 50 pivotably secured to the covering plate 22, a trigger 55 fixed to a joining point of one portion of the ejector 50 and the other portion thereof and provided on a top of the covering plate 22, a pivot bar 51 pivotably secured to the covering plate 22 and having a downward extending peg 511 at one end, the peg 511 adapted to engage with one end of one portion of the ejector 50 as a stop in an inoperative position of the mechanism, a spring 53 in the form of a wire having one end secured to one end of the pivot bar 51 and the other end secured to one end of the other portion of the ejector 50, a link 52 having one end formed as a bent pusher 521 extending through the first channel 211 into a space defined by the casing 1 and the cover 2 in proximity to the other corner at the front end opposing the outlet 11, and the other end pivotably secured to one end of one portion of the ejector 50, and an elongate sliding member 54 having a lower portion extending through the second channel 212 into the space of the cigarette case to block the outlet 11 when the cigarette case is closed, and the remaining portion hidden in the space defined by the covering plate 22 and the separation plate 21, the sliding member 54 having its midpoint pivotably secured to the other end of the pivot bar 51, and the sliding member 54 adapted to move back and forth along the second channel 212 in cigarette ejecting operation as detailed later.
A cigarette ejecting operation of the invention will be described in detailed below by mainly referring to
A bottom of the casing 1 is inclined forward. That is, a rear portion of the bottom of the casing 1 has an elevation higher than that of a front portion thereof. This can automatically push an adjacent one of any remaining cigarettes 3 toward the empty zone 12 at the end of the cigarette ejecting operation. As a result, a cigarette 3 (if any) in the cigarette case is always disposed on the zone 12.
To the contrary, a releasing of the pivoting force exerted upon the trigger 55 will automatically return all components of the mechanism to their inoperative positions because the spring 53 exerts an expansion force to counterclockwise pivot the ejector 50 (see
A cigarette loading and ejecting operation of the mechanism will be described in detailed below. First, a smoker may push the frame 14 toward the rear end of the casing by compressing the elastic member 16 until the latch 152 enters the recess 141 and passes the ramp 142 into the slot 143 for being locked therein. Next, the smoker may put a plurality of cigarettes into the space defined by the frame 14 and the casing. Next, close the cover onto the casing after loading the cigarettes. The spring 153 is thus compressed because the bottom of the cover presses the button 151 and the latch 152 thus retracts outward to clear the slot 143. Hence, the frame 14 is unlocked. The frame 14, as always pushed by the force exerted thereon by the elastic member 16, will automatically push an adjacent cigarette to occupy the empty space left by the cigarette which has been ejected from the cigarette case at the end of the cigarette ejecting operation as described above.
While the invention herein disclosed has been described by means of specific 25, embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
